To all 'whom it may cmwerr:

Be it known that 1. ARNOLD Mom'mm, a citizen of the Swiss Confederatio m residing at Ober-Winterthur, Switzerland; have invented certain new and useful Improvements in Coke-Quenching Process (for e which I have filed anapplication for a pat- I ent in Germany July 7, 1919), of which the following is a specificaton.

This invention relates to a process for cooling the hot residues from a number of distilling vessels with utilization of the heat contained in the residues and consisting in collecting the hot residues, instead of bringing. the same from each individual distilling vessel into a separate cooling, vessel 'as has been done hitherto, in a common cooling vessel adapted to be emptied successively, for the purpose to ensure a continuous and approximately constant supply of heat from the residues coming from the different distilling vessels.

In the accompanying drawin the invention is shown by way of exam e;

Fig. 1 shows in elevation a p ant for cooli coke with the distilling ovens.

ig 2 is diagram of the process as used present. Fig. 3 illustrates in adiagram the process according to this invention.

a designates a battery of coke ovens with the vertical distilling retorts b, c is the cooling vessel for collecting the coke from all retorts and d is a transporting receptacle provided -with a discharging device e, which receptacle can be carried below all the retorts by means of a truck to be raised above the cooling vessel with t e aid of the hoist h adapted t'o run on rails g. After the completion of the distilling process the retorts are emptied separately or in groups into the receptacle d. This receptacle is lifted upon the cooling vessel' by means of the hoist and emptied into said vessel whereupon it is loaded again,' this being repeated as often as neoesary. The heat -can be drawn ofl and carried to the places where it is to be utilized by means of a gas-current circulating through the residue and paxing through a device k for exchanging the heat, here a steam boiler; the successive removal of the residues which have been cooled already and which form the lower layers in the vessel, being efl'ected by opening an outlet or dischargng device z which is arranged in the bottom of the cooling vesel. The heat which' has been drawn ofi from the residues can be used for the generation of steam or for similar urposes. In comparison with the known met ods, according to which the residues from one distilling vessel are emptied into a. separate cooling vessel, said cooling vessels havng'to be completely emptied before a new char e of residues can be put in, so that the supp y of heat to the place where it is to be utilized is intermittent and cannot be regulated ac-` cording to re uirement, the process according to this nvention has the advantage that it ensures a continuous, approximately uniform supply of heat from the residues coming from the different distilling vessels;

The inert coolin medium is introduced through a pipe 1- %y means of a centrifugal blower p, and is withdrawn through pipe s. The heated medium is pawed through ,a steam boiler such ,as shown at k, and returned again to the blower p.

In Figures '2 and 3 which permit to compare the known process with the procem according to this invention, the storing receptacles for the material to be distilled are designated by i; the distilling vessels by b, the cooling vessel for the residues from distillationby c, and the place where th heat is to be utilized, e. g. the boiler, by k. Whilst according to the process used hitherto, the heat is supplied intermittently from the-distilling vessels to the place where it is to be utilized," this heat is, according to the improved process, collected as soon as it gets out of the distilling vessels, in a common vessel c to be supplied to the place Where it is to be utilized according to requirement. If there are a great number of distilling ovens there could of course be used two or three cooling vesels instead of the common cooling vessel hereinbefore described, each cooling vessel serving for a separate group of coke ovens. i

I claim 1.- The process of cooling the hot residues from a plurality of dist-il ing vessels with recovery of the heat contained within the residues, characterized in that the hot residues at obviously varying temperatures from a plurality of distilling vessels are cooled in a common receptacle or cooling vessel large enough to receive the whole contents of said distilling vesels for the purpose of stoning up the 'residues and equalizing the temperature thereof, whereby a constant and um'form sup ly of heat may be obtained and the cool or cooling resdues may be removed at will.

2. The process for cooling the hot resi- 5 dues from a plurality of distilli 'vessels with recovery of the heat containe within the residues, comprising emptyngthe hot residues of obviously varying temperatures from a plurality of distilling vessels into a 1 common reoeptacle large enough to receive the' contents from more than one of said distilling vessels,' storing and equalizing the temperatures of said residues in said receptacle, cooling the said residues in said re-. ceptacle by a heat exchange, and removing 15 the cooled residues from said receptacle.

In testimony whereof I aflix my signature in the presence of two witnesses.
